Abstract: A removably attachable traction gear for the underside of footwear having two primary components: a retaining member and a receptacle. These two components respectively replace the common screw and threaded receptacle systems found in for affixing traction gear to the underside of shoes. A partial turn of the traction gear securely locks the gear into the receptacle. The retaining member has a three-extension design so as to make the traction gear resistant to lateral forces applied to the ground-engaging end of the cleat. Locking is achieved through use of cantilevered fingers which press in during installation of the retaining member, and which spring back out to lock with mated indentations in the extensions. During installation a dome containing insole material is compressed. Unlocking is achieved through reverse turning the retaining member to force the springs back in, and removal is aided through re-expansion of the dome.

Abstract: A plastic tab for indexing or marking a folder or an edge portion of an article such as an organizer or storage system. The lower portion of the tab has two downwardly extending walls, between which an edge of the folder or other article may be placed. The downwardly extending walls are configured and adapted to create an interference fit when the folder or other article is inserted between the walls of the tab. The interference fit enables the tab to remain securely in the desired position along the edge portion. The tab is made of a flexible polymeric material so that it may be mounted, re-positioned or removed easily. Removal of the tab from a wall edge causes the walls to flex apart and thereby eliminate or minimize the interference fit between the tab lower walls and the article on which the tab is mounted. Removal of the tab is therefore a smooth and simple operation that minimizes breakage of the tab or damage to the folder, organizer or storage medium.

Abstract: A New Useful Improvement. An encapsulation method for producing high quality low cost housing panels, which uses commercially fabricated pre-assembled light gage steel framed structures, with superior insulation material. The encapsulation process uses a Clamshell Jig Fixture designed specifically for this process. The pre-assembled steel housing frames are placed in the Jig Fixture and sealed. Thereafter the insulation material is injected into the steel framework via openings in the jig fixture. The insulation material is a high density Class 1 Isofoam Polyisocyanate, known as Polyurethane. It is free of Formaldehyde and CFC's or HCFCS. Its insulation “R” factor is 7.69 per inch of thickness. Finished panels result in “R” factors to 40.37, with vertical, horrizontal, wind and seismic strengths greater than building code requirements for housing. Panel attaching methods are simpler and stronger using smaller, short, light 16 to 12 gage studs, bolts, nuts and anchor plates.
